One of the best things you can do for your Mom and her health is to keep exact records, When you go to the doctor and they want to do a test remind them when that test was done last . I had a patient, that his mother liked to have multiple tests done on him. The best way to deal with her was to remind her that this doctor said the same thing, that this test was just done. You won’t have the guilt either, because you know this or that was checked. My Dad loves the attention the Doctors give him. When he was young he had a disabled brother and probably sometimes he was ignored. Then he got polio at a young age and got all kinds of attention. So that is my theory as to why he loves the doctor. Thank God he still drives himself, and has good insurance. Maybe look for another way for her to get attention. Who knows, it might work. I find the sicker my Mom is the more Dad needs to go to the doctor. Is there a senior center , or a popular restaurant that older people hang at, thats the place to take Mom. Is this something new, maybe she is afraid of dying. Talk to her about her medical concerns, is she religious, maybe she needs a priest, seriouslly.
